PACKING-CASE.

Specificationof Letters Patent. Patented Mar, 14, -1-911. Application filed February 9, 1909. Serial 1;. 478,899.

To all whom it may concern:

Be it known that I, JOHN H. K'ILLIoN, a citizen of the United States, residing at Chica 0, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Packing- Cases, of which the following is a specification.

The principal ob ect of my invention is to 'provide a new and improved sheet metal packin ,case.

Anot er ob ect is to provide a sheet metal packing case that canbe knocked down when an t and tion takenwith 1th all these objects in view, the inve'ntion consists structure.

cking can have its parts quickly assemm operative relation when desired. Another object is to provide a sheet metal packing case that shall have great strength in proportion to the quantity of material emgloye I ther objects will be more readily apparent in connection with the following specificathe accompanying drawings.

of the combination of elements recited in the appended claims.

In the accompanyin drawings, I have illustratedone particuar embodiment of my invention wh ch is one of several 'forms thereof preferredby me at the present time. I have also illustrated in the drawin s a modification with- }figure 1 is a perspective View showing the various case slightly spaced apart. :Fi 2 1s a longitudinal section when assemb ed.

[lliepside wall 15 of the barrel consists of a s ngle sheet of metal corrugated longitudi nally ofithe barrel. The corrugations are madea, little deeper toward the ends 17, so

then to thattlie perimeter of the barrel is less at the ends than at the central part 16. Before the sheet 15 is corrugated its ends are folded inwardly as indicated by the reference "numer'al's-lS. Also folds or tucks-19 are made Fig, 2. The folded The longitudinal meeting edges of the side wall sheet 15 will now be described. One edge is folded back-on the outside, as indicated b the referencenumeral' 20, and is ded forward again as indicated by I died The main part 23 of each head is corru ated socket 28 the threaded erid 31 of respect to a detail 0 the.

which is ada ted to receive the sod ed' e 22 of the sid wall sheet 15. oppo g. I The two heads of the barrel are alike and they are preferably stamped by means of in the shape shownin the drawings.

slightly in concentric circles, thus faci itating a slight degree of yielding without rupture. i round the circumferential border 01f the head. 23 is a groove ortrough 24, its

width being substantially equal to the depth of the corrugations attheends of 'the'side wall 15. This trou h 24 is bordered onthe outer side by a fla irge 25tha-tlaps down around the s1de wall 15. Holes 36 are made centrally heads. A com ound nut 27'301s permanently attached in one of these holes. This nut consists-of a cylindrical body 27 having in the two aninternally threaded socket-28 and an ex:

ternally threaded' projection 2.9"adapted 't-o pass through the hole 36 and'have the nut 30 screwed tight on the outside. Into this tudinaltie-rod 33. may be screwed.' e

other threaded end 31 0f the tie-rod 33- will project through the oppositeholefifi, where it can receive a nut 32 on'th'e outside, and thus tie the heads 23-together. If deemed desirable, the heads can be further secured in place by providing a circumferential series of notches 34 in the outer corrugations around the ends of the sidewall 15. Then a groove26is formed around the outside of the flange 25 of the head 23, this groove 26 on the outside making a head 35 on the'inada ted to fit into the notches 34 when the arre is assembled;

The process of manu gated sheet metal side walls 15, naturally delivers them in curved shape ,withthe longi.-'

t'udinal edges s aoed apart somewhat more widely than is s own in Fig. 1. Thus, these sheet metal side walls 1 5 can be readily nested for shipment.

heads 23 will also host readily, and. thus a large number of these barrels can be acked in a small space for shipmentw en in knocked-down condition.

To assemble the barrel, the meeting. edges 20-21 and 22 of the side wall are matched together as already. e lained. Then the lower-head 23 is applied? the compound nut 27-3 0 having factoring the corru-' [It will be seen that the p the ion been previously assembled in impairin its utility, an the the hole 36. Next the tie-rod 33 is screwed into the socket 28. The lower head and the side wall havin been assembled, the barrel can be filled Wlfil whatever commodity it is intended to receive, such for example as dry powdered cement. Then the upper head 23 1s applied, the end of the tie-rod 33 pro ecting t rough the hole 36, and finally the nut 32 is screwed on, thus securely t mg the barrel heads together, and also t rough ,them securing the side wall 15. The annular grooves 24 in the heads 23 brace the ends of the side wall 15 against either inward or outward displacement.

When his desired to open the barrel, the

nut 32 can be withdrawn ,and the head 23 lifted up. If it is desired to let the barrel stand and to remove its contents with a scoop, the tie-rod 33 can be unscrewed from the socket 28 and lifted out, thus removing an obstruction that might otherwise be .0 cred to the scoop.

- It will be seen that the particular embodiment of my invention which I have described and illustrated in the drawlngs is adapted to satisfy the objects stated at the beginning of this specification. {This barrel has the advantages that a plurality of them can be readily nested v knocked down condition, that the parts of a single barrel are few and simple, and that they can be quickl and easily assembled into operative relation or receivin a desired commodity. Thecorrugation o the side wall and the convexity thereof give great strength in pro ortion to the amount of material emloye The strength is further increased y the inturned end lips 18 and by the folds or hoo s19.

.Thearrel can be easily opened when desired without destroyin any part of it or arts can again be assem led, so that it can be used repeatedly. At any stage of its use, if desired, it can be knocked down and then later on completely reassembled.

The beads 35 on the flanges 25 of the heads 23, in conjunction with the notches 34 in the corrugations on the side wall 15, assist in holding the parts together. In some cases it ma be desirable to'dispense with the beads an the notches, and rely wholly upon the central tie-rod 33.- In other cases, it may be desirable to dispense with the central tierod and de endwholly upon the beads. and notches to eep thepartsto ether. And in still other cases it may be esirable to use both means simultaneously.
